Features of eccentric rotary valve

Long seat life. Durable and strong metal or ceramic seat sealing ring and eccentric valve core reduce the friction between the valve core and the valve seat during the opening and closing process, and improve the damage of the valve seat sealing surface and the resistance when opening. When the valve core rotates to the closed position, the valve core and the valve seat sealing ring will automatically overlap, so that the sealing surfaces can get a more reasonable fit. The material of the seat sealing ring can be 316 stainless steel, A105 forged carbon steel surfacing hard alloy and ceramics. The spherical surface compresses the valve seat, which is easy to destroy the crystalline stutter. It is suitable for the occasion of crystallization, stuttering and dirty media.

Reliable performance. The special valve seat sealing ring design can automatically center, self-lap, and dynamically align with the valve core, which can increase the service life. Sealed metal bearings can prevent particles from accumulating on the shaft surface and prevent the valve core from rotating. The flow path is simple, the Kv value is large, and the self-cleaning performance is good.

Multiple operations are possible. The self-centering valve seat sealing ring and sturdy valve core can achieve sealing when used in either direction of forward flow or reverse flow. Using the backward flow direction, the outlet turbulence zone is far away from the valve seat sealing surface. In addition, the 90°C stroke of the valve core also helps to reduce the erosion of the valve core and the flowing medium and reduce the possibility of damage. Suitable for two-position control.

Easy to install. The valve body with flange can be connected with different grades of pipeline flanges. In accordance with different design requirements, exposed flange screws can also be avoided. The positioning surface and overall effect during installation are also better. A compact flangeless valve body can also be provided, which can be positioned by flange screws during installation. Small size and light weight.
